When it comes to claiming car mileage for business use, the process can seem daunting. However, the HM Revenue & Customs (HMRC) has simplified this process with their car mileage claim form. This form allows you to claim tax relief on the cost of fuel and vehicle maintenance, making it an essential tool for self-employed individuals and employees who use their personal vehicles for work.

Before delving into the specifics of the HMRC car mileage claim form, it's crucial to understand that you can only claim for business journeys. This includes trips between your home and your permanent workplace, as well as any other business-related travel. You cannot claim for journeys between your home and a temporary workplace.

Understanding the HMRC Car Mileage Rates
The HMRC provides fixed mileage rates for cars, motorcycles, and commercial vehicles. These rates are updated annually and are intended to cover the cost of fuel, vehicle maintenance, and depreciation. Using these rates can simplify your claim process, as you won't need to keep detailed records of your fuel and maintenance costs.

For cars and vans, the mileage rates are as follows (as of 2021/22):
- 45p per mile for the first 10,000 miles, then 25p per mile thereafter for cars or vans
- 24p per mile for motorcycles

Using the HMRC Car Mileage Rates
To claim using the HMRC car mileage rates, you'll need to keep a record of the number of business miles you've driven. This can be done using a simple logbook or a dedicated mileage tracking app. Once you've calculated your total business miles, you can multiply this number by the appropriate mileage rate to determine your claim.
For example, if you've driven 12,000 business miles in your car, you would calculate your claim as follows:

- First 10,000 miles: 10,000 miles * 45p/mile = £4,500
- Remaining 2,000 miles: 2,000 miles * 25p/mile = £500
- Total claim: £4,500 + £500 = £5,000
Claiming Actual Costs
Instead of using the HMRC car mileage rates, you can choose to claim the actual costs of running your vehicle for business. This method requires you to keep detailed records of all fuel and maintenance costs, as well as receipts for any purchases. You can then claim a proportion of these costs based on the number of business miles driven.

While claiming actual costs can potentially lead to a higher claim, it also requires more administrative work. You'll need to keep track of all your expenses and ensure that your records are accurate and up-to-date. It's also important to note that you cannot claim for any personal use of your vehicle when using this method.
Filling Out the HMRC Car Mileage Claim Form




















Once you've calculated your claim, you'll need to fill out the HMRC car mileage claim form. This form is available to download from the HMRC website and can also be filled out online. The form requires you to provide details of your vehicle, including its make, model, and engine size, as well as your business mileage for the period.
If you're claiming using the HMRC car mileage rates, you'll simply need to enter your business mileage and the appropriate rate. If you're claiming actual costs, you'll need to provide a breakdown of your expenses, including fuel, maintenance, and any other running costs.
Submitting Your Claim
Once you've filled out the form, you can submit it to the HMRC. If you're an employee, your claim will be submitted through your employer. If you're self-employed, you'll submit your claim directly to the HMRC as part of your self-assessment tax return.
It's important to note that you can only claim for business journeys, and you must keep accurate records of your business mileage and expenses. The HMRC may ask to see these records at any time, so it's crucial to keep them safe and up-to-date.
In conclusion, the HMRC car mileage claim form is a valuable tool for claiming tax relief on the cost of running your vehicle for business use. By understanding the HMRC car mileage rates and keeping accurate records, you can ensure that you're claiming the correct amount and maximizing your tax relief. If you're unsure about any aspect of the claim process, it's always a good idea to seek professional advice to ensure that you're complying with HMRC guidelines and maximizing your tax relief."
